plot library python code example

Example 1: python plot

import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4], [1, 4, 9, 16])
plt.show()

Example 2: plot in python

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_axes((0.1,0.4,0.5,0.5))

ax1.set_title('Title of Plot')
ax1.set_xlabel('X')
ax1.set_ylabel('Y')

ax1.plot(X,Y,c='black',linestyle='--',linewidth=0.5)
ax1.scatter(X,Y,c='red',s=0.5)
ax1.legend(['Line','Scatter'])

ax1.xaxis.set_ticks([0.0,0.1,0.2,0.3])
ax1.yaxis.set_ticks([0.0,0.1,0.2,0.3])

ax1.grid(which='major')
ax1.tick_params(direction='in')

txt = 'Write something on the graph page\
		\n over one or more lines.'

fig.text(0.5,0.05,txt,ha='center')

fig.savefig('Figure.pdf')

Example 3: matplotlib

# importing matplotlib module  
from matplotlib import pyplot as plt 
  
# x-axis values 
x = [5, 2, 9, 4, 7] 
  
# Y-axis values 
y = [10, 5, 8, 4, 2] 
  
# Function to plot scatter 
plt.scatter(x, y) 
  
# function to show the plot 
plt.show()

Example 4: python matplt

import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4])
plt.ylabel('some numbers')
plt.show()
